Man, I never knew that either! I've side-stepped the problem now by 
switching to a Firewire interface for JACK, but before that, I'd tackled 
it by explicitly numbering the cards at module load time through a file 
in /etc/modprobe.d.

That solution actually worked well, and it was easy when I just had one 
USB device (and a couple of PCI ones). I have four USB devices now, and 
while it still works, the module options look a little ridiculous:

options snd-usb-audio index=3,4,5,6 vid=0x12e6,0x15ca,0x0471,0x0944
    pid=0x0013,0x0101,0x0329,0x010f
